The Orlando Sentinel reports that Orange County, Florida, is undertaking a sweeping effort to snoop on the social media communications of the county's public school students and staff, for the nebulous task of "[ensuring] safe school operations," and say they will use the software (at a license cost of about $13,000 per year) "to conduct routine monitoring for purposes of prevention or early intervention of potential issues where students or staff could be at risk to themselves or to others." The software they're using is from Snaptrends, which offers "location-based social media discovery." According to one of the comments attached to the linked story, there are monthly fees, in addition to the annual licensing cost.

wrp103 links to the BBC's report of a newly engineered alloy that returns to its original shape after deformation even after 10 million cycles more than 10 million times. From the article: "Memory shape alloys" like this have many potential uses, but present incarnations are prone to wearing out.
The new material — made from nickel, titanium and copper — shatters previous records and is so resilient it could be useful in artificial heart valves, aircraft components or a new generation of solid-state refrigerators."

An anonymous reader writes: I am a software engineer with over 10 years of experience making approx 210k a year after bonus. I've seen countless of software engineering jobs off-shored or taken by H1Bs over the past 5 years. While I am pretty safe at my current job, software engineering as a profession is beginning to look bleak, and i am not even sure if I can ask for the same money if I decide to jump ship to another company (I live in an expensive area).

A friend of mine who works as a network architect with dual CCIEs have no problem finding/landing jobs with high salary. His profession doesn't seem to be affected by outsourcing or H1bs, so I am tempted to switch from my field to networking for better stability and greener pastures.

So the question is, should I do it? The reason why I am looking for the long-term stability is because I've a family of 3 to feed. I cannot afford to be jobless for more than 3 months if I do get laid-off, and software engineering doesn't seem to be the profession after years of observation to provide long-term stability.

NVIDIA SHIELD Android TV Reviewed: Gaming and Possibly the Ultimate 4K Streamer 40

Posted by timothy
from the ensmallening-rocks dept.
Earlier this week, NVIDIA officially launched its SHIELD Android TV set-top device, with far more horsepower than something like Roku or Apple TV, but on par with an average game console, and at a more affordable price tag of $199. MojoKid writes: What's interesting, however, is that it's powered by NVIDIA's Tegra X1 SoC which features a Maxwell-derived GPU and eight CPU cores; four ARM A57 cores and four A53s. The A57 cores are 64-bit, out-of-order designs, with multi-issue pipelines, while the A53s are simpler, in-order, highly-efficient designs. Which cores are used will depend on the particular workload being executed at the time. Tegra X1 also packs a 256-core Maxwell-derived GPU with the same programming capabilities and API support as NVIDIA's latest desktop GPUs. In standard Android benchmarks, the SHIELD pretty much slays any current high-end tablet or smartphone processor in graphics, but is about on par with the octal-core Samsung Exynos in terms of standard compute workloads but handily beating and octal-core Qualcomm Snapdragon. What's also interesting about the SHIELD Android TV is that it's not only an Android TV-capable device with movie and music streaming services like Netflix etc., but it also plays any game on Google Play and with serious horsepower behind it. The SHIELD Android TV is also the first device certified for Netflix's Ultra HD 4K streaming service.

They compare this to a watchmaker's sonic screwdriver. So far, though, the practical applications include cell sorting and low-power water purification, rather than TARDIS operations. Appropriately enough, one of the researchers is named Bruce Drinkwater.

jan_jes writes: MIT researchers demonstrated an untethered miniature origami robot that self-folds, walks, swims, and degrades at ICRA 2015 in Seattle. A miniature robotic device that can fold-up on the spot, accomplish tasks, and disappear by degradation into the environment promises a range of medical applications but has so far been a challenge in engineering. This work presents a sheet that can self-fold into a functional 3D robot,actuate immediately for untethered walking and swimming, and subsequently dissolve in liquid. Further, the robot is capable of conducting basic tasks and behaviors, including swimming, delivering/carrying blocks, climbing a slope, and digging. The developed models include an acetone-degradable version, which allows the entire robot's body to vanish in a liquid. Thus this experimentally demonstrate the complete life cycle of this robot: self-folding,actuation, and degrading.

Third Stage Design Problem Cause of Most Recent Proton Failure 63

from the no-richard-feynman dept.
schwit1 writes: The Russian investigation into the latest Proton rocket failure has concluded that the failure was caused by a design failure in the rocket's third stage. The steering third stage engine failed due to excessive vibration as a result of an imbalance in a rotor of a pump unit. While it is always possible for new design issues to be discovered, I wonder why this problem hadn't been noticed in the decades prior to 2010, when the Proton began to have repeated failures.

retroworks writes: Integrated photonic devices are poised to play a key role in a wide variety of applications, ranging from optical interconnects and sensors to quantum computing. However, only a small library of semi-analytically designed devices is currently known. In an article in Nature Photonics, researchers demonstrate the use of an inverse design method that explores the full design space of fabricable devices and allows them to design devices with previously unattainable functionality, higher performance and robustness, and smaller footprints than conventional devices. The designed a silicon wavelength demultiplexer splits 1,300nm and 1,550nm light from an input waveguide into two output waveguides, and the team has fabricated and characterized several devices. The devices display low insertion loss (2dB), low crosstalk (100nm). The device footprint is 2.8×2.8m2, making this the smallest dielectric wavelength splitter.

ckwu with word that South Korean researchers have created the first UV-emitting quantum dots, and employed them in the creation of a flexible LED. Their achievement is notable because no one has previously succeeded in making quantum dots capable of emitting light at wavelengths shorter than 400 nm, which defines the upper range of the UV spectrum. Writes ckwu: To get quantum dots that emit UV, the researchers figured out how make them with light-emitting cores smaller than 3 nm in diameter. They did it by coating a light-emitting cadmium zinc selenide nanoparticle with a zinc sulfide shell, which caused the core to shrink to 2.5 nm. The quantum dots give off true UV light, at 377 nm. An LED made with the quantum dots could illuminate the anticounterfeiting marks on a paper bill. The article names a few applications of the technology, besides, including water sterilization and industrial applications.

agent elevator writes: IEEE Spectrum has a feature (part of its Hacking the Human OS issue) on the future of vagus nerve stimulation, a device-based therapy with the potential to treat a ridiculously wide variety of ailments: epilepsy, depression, stroke, tinnitus, heart failure, migraines, asthma, the list goes on. One problem is that, because it required an implant (a bit like a pacemaker), it was never anybody's first-choice therapy. But now there's a non-invasive version, a device you just hold to your neck twice a day for a few minutes. It's being trialed first for migraines and cluster headaches (which sound horrible). If it works, vagus nerve stimulation could compete directly with drug treatments on cost and convenience and it would let doctors find new ways to hack human physiology.

ClockEndGooner writes: A study conducted by the Netherlands Organization for Applied Scientific Research found that low frequency and long wavelength jet engine droning noise was significantly reduced in the fall after farmers plowed their fields near Amsterdam's Schiphol Airport. The remaining furrows "had multiple ridges to absorb the sound waves, deflected the sound and muted the noise." This led to the development of the Buitenschot Land Art Park, a buffer park featuring "land art" that has significantly reduced aircraft noise without requiring cuts in the number of allowed flights in and out of the airport. The land art park has also provided neighbors with additional recreational paths and sports fields in the same space.

baegucb sends a followup to the news from March that professional internet trolls were operating by the hundreds at factories in Russia. A woman hired to be one of these trolls, Lyudmila Savchuk, spoke to the media about her job, which led to her being fired. She's now suing her former employer and providing further details about how they operate. "The 'troll factory' operates based on very weird schemes, but all those firms are connected to each other, even though they are separate legal entities," she said. "I knew it was something bad, but of course I never suspected that it was this horrible and this large-scale." She describes how they flooded comment sections with pro-Putin responses, pushed out over 100 blog posts each shift, and doctored images to suit their employers' needs. Savchuk is now gathering activists to oppose this form of internet propaganda.

itwbennett tips news that Uber has amended its privacy policy, making it much simpler to read and understand. But the policy also includes changes to what data Uber collects about its riders. Beginning July 15th, the Uber phone app will keep track of a rider's location while it's running in the background. Uber says riders will be able to opt out of this tracking. The policy changes also allow for advertising using the rider's contact list: "for example the ability to send special offers to riders' friends or family." The revision of Uber's privacy policy followed complaints at the end of last year that the company was overstepping its bounds.

Though emails about the thermal imaging systems date back as far as 2006, the plans to acquire them began in earnest much more recently, in 2013. To try to hide Russian involvement, a company called Cyclone established a new company in the Republic of Cyprus. They did so with the help of a company called Rayfast, which was owned by three other companies itself. After obfuscating the new company's ownership and military ties, they reached out to several Western companies who worked with the technology.

The FBI indicted Beauregard Wattigney yesterday for wire fraud and trademark counterfeiting on digital black market sites Silk Road and Silk Road 2. Wattigney allegedly spoofed coupons for dozens of products and sold collections of them online in exchange for Bitcoin. The FBI accused him of doing $1 million worth of collective damage to the companies he made coupons for, but a fraud consultancy believes the total financial cost of his actions was much higher. Wattigney also offered expensive lessons that taught people how to make their own coupons. "In his tutorials, [he] explained the simple breakdown of barcode creation using the increasingly universal GS1 standard: GS1 codes begin with a 'company prefix' that can be copied from any of the company's products. The next six digits are the 'offer code,' which can be any random number for a counterfeit coupon, followed by the savings amount listed in cents and the required number of item purchases necessary to receive the discount."
